Selection And Research Of Boiler Flue Gas Desulphurization Technology In Thermal Power Plant Of Liaohe Oil Field

In 2014, Chinese government put forward one of the focus of the current environmental protection work is for control of sulfur dioxide pollution, sulfur dioxide pollution prevention and control in our country, control the thermal power plant, industrial boilers and kilns and other three items of smoke gas emissions is the key. At present, there are mainly three kinds of coal desulphurization method in domestic and abroad. One is that the former is burning, the two is the burning of sulfur and sulfur, and the three is that the flue gas desulphurization technology（FGD） is the main way to solve the pollution of flue gas emissions.The thermal power plant of Liaohe Oilfield has a late start, and the existing equipment has low efficiency and can not reach the discharge requirements. If you want to keep on living, it is necessary to find a suitable technology.The main research content of this paper is to consider the specific objective conditions of the thermal power plant of Liaohe oil field by the comparison and analysis of the domestic and foreign fire power plant desulphurization technology.In the scheme of the concrete implementation phase, gas for heat exchanger install the necessary discussion, determine the investment necessary; carried on the design to the desulphurization tower of the main parameters, calculating to ensure higher desulphurization efficiency when the minimum reactor size; in addition to mist eliminators for self transformation, by increasing the strong polypropylene instead of stainless steel, so as to decrease the corrosion caused by the impact; the absorbent conveying pipe upgrade; choose the suitable SO₂ emissions statistics method; desulphurization system debugging.Finally, the system is operating normally, and the SO₂ content of the flue gas is less than 200 mg/Nm³, so the expected target is achieved.
